SHOE.

Specification of Letters Patent.

Patented Oct. 5, 1920.

Application filed January 17, 1918. Serial No. 212,291.

To all whom it may concern:

Be it known that I, MEYER S. Hnss, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Shoes, of which the following is a specification, reference being had therein to the accompanying drawing.

The present invention relates to improvements in shoes, and has for its general object to improve the construction of shoes as re-- gards durability, comfort, water proofing qualities, and, furthermore, to provide a construction which will render the art of shoe repair a comparatively easy and practical operation, in. so far as the restoring of the inner face of the insole structure is concerned.

With these general objects in view, the invention consists in the provision of a secondary insole or layer firmly fixed within the shoe and covering the entire upper face of the usual insole, said secondary insole acting as a reinforcement tothe usual insole and being held in its fixed relation by means of the stitches which secure the upper to the usual insole and welt.

Provision is also made whereby this secondary insole or layer may be easily removed or ripped from its normal fixed position within the shoe, so that in the event the same becomes worn or otherwise in such a condition as to be no longer able to perform its function as an insole, it may be replaced by another layer, body or filler, as for instance by the method set forth in my co-pending application, Serial Number 195 127, filed October 8, 1917, or, in fact, in any preferred manner, and thus restore the shoe to a condition where it is in strict conformity with the original last;

Furthermore, the invention consists in the provision of a cushion sole, the cushion for said sole being incased between he secondary insole or layer and the usual insole, whereby said cushion is protected to a material degree from moisture and held in a compact and uniform condition and preven ed from shifting to such an extent as to cause wrinkles or bunches, as is the tendency with the ordinary cushion sole.

A still further and important feature of the invention is the provision of a waterproof seam between the upper and the usual insole, a flexible strip of rubberized or other waterproofed material being inserted between the upper and the edge of the usual lnsole at a point where these two elements are stitched together, thereby preventing any moisture passing through the seam. in connection with this waterproofed strip 1t may be noted that this strip is also stitched to the edge of the secondary insole or layer by means of a hidden seam, and thereby forms the means of firmly holding the layer in its fixed position within the shoe.

Further advantages and purposes of this invention will be apparent from the detailed description of the present embodiment thereof, taken in connection with the accompanying drawings, wherein:

Figure 1 is a longitudinal section through a portion of a shoe embodying my invention;

Fig. 2 is a transverse section of what is shown in Fig. 1, the section being taken on the line 2-42 of said figure;

Fig. 3 is an enlarged detail sectional view, showing particularly the manner of securing the secondary insole within the shoe, and the manner of making a water proof seam at this point;

Fig. a is an enlarged detail perspective view of the secondary insole and its means of attachment, and

Fig. 5 is a transverse sectional view of a portion of a shoe, embodying my invention, but without including the cushion shown in Figs. 1 and 2.

Referring to the drawing, in Figs. 1, 2, 3 and 5 is shown a shoe comprising the usual upper 1, insole 2, welt 3, an outer sole 4, the usual filler 5 between the insole and outer sole, and at 6 is illustrated a secondary insole or layer embodying the invention.

This secondary insole or layer 6 is preferably made of a chemically prepared felt, although any desired material may be used, and in the present embodiment of the invention said layer is adapted to cover the entire upper surface of the usual insole and form a reinforcement therefor. Furthermore, said layer 6 serves as a covering for any of the irregularities appearing around the edges of said usual insole 2, which irregularities are formed during the construction of the ordinary welt shoe and by the curling up of said edges during the ordinary use of said shoe. In this connection, it is to be noted that the edges of the layer or secondary insole, due to the particular means herein disclosed of fixedly securing said layer within the shoe, are firmly held in take on the usual appearance of shoes asordinarily made.

The particularmeans referred to for se curely attaching the secondary insole 6 in firm position within the shoe, consists of a flexible strip 7 which in the present instance is a rubberized or other waterproofed strip secured along the edges of said layer and sewed to the underside thereof by means of a hidden seam, as clearly shown in the drawings, which strip in turn is positioned between the usual insole 2 and the upper 1 and firmly held in place by means of the stitches which secure said insole 2. the upper and the welt in fixed relation, one with the other. Thus it will be seen that the strip 7 forms an efiicient fastening means for securing the layer 6 in firm and fixed relation within the shoe, and the edges ofsaid. layer due to this particular type of securing means are prevented from curling up and presenting the usual irregularities so common in shoes of the ordinary make. It will be observed that the edges of the layer 6 are split, as at 8, and that the waterproofed strip 7 is sewed or stitched only to the lower split portion 9, after which the split portions are cemented or vulcanized together, thus forming the hidden seam to which reference has been made.

The flexible strip 7 in addition to its use as a means for fastening the layer or secondary insole in fixed relation within the shoe, also serves a useful and important function as a means'for bringing about a waterproof seam between the usual insole, upper and welt, and thereby preventing any moisture from passing by said seam and entering the interior of the shoe. In this connection, it will be noted that the flexible strip ismadei of rubberized or other waterproofed material, and, therefore, due to the nature of this material, said strip closes tightly around the stitching threads and also closes the holes made by the needle and awl in the process of sewing, so that a complete waterproof seam is provided, said strip cov' ering the edges of the usual insole and lying between the same and the upper, as clearly illustrated in the accompanying drawing.

By the use of my improved secondary insole or layer, as shown at 6, I am enabled to make a cushion sole of superior character, one in which the cushion will not in any way be affected by moisture, and, furthermore,

It is desirable to reduce where the cushion will be prevented from stretching or moving within the shoe to such an extent as to cause wrinkles or bunches, which is the usual tendency with the ordinary type of cushion sole. In the present instance, the usual insole 2 is dished, as at 10, to receive the cushion 11, and this cushion, it will be observed, completely fills this dished portion, and lies between said insole 2 and the layer 6, in which position it is inc-ased be tween these last two mentioned elements and firmly held in a compact and uniform condition throughout the life of the shoe. The two insoles, in reality, constitute a closed envelop for the cushion, as the edges of said insoles are securely united together with a waterproofed strip between said edges, in which event moisture of any kind is prevented from coming in contact with the cushion, which may be a specially treated felt of plastic material capable of being molded to the desired shape of the last'in unison with the insole structure, such, for instance, as that disclosedin my said co pending application.

The dishingof the'insole 2, aside from providing a place to receive the cushion, permits the use of the cushion without increasing the dimensions of the shoe between the lower face of the outer sole f and the upper face of the secondary insole or layer 6.

In my co-pending application, Serial Number 195427, heretofore referred to, considerable comment has been made in connection with the use of a layer or secondary insole for shoes, and the necessity for the renewing or repairing of the insole structure after the same has become badly worn. In this connection it may be again stated herein that the results of wear produced by any particular wearer are such that unless the inner face of the insole structure or that face of the shoe which comes in contact with the bottom of the wearers foot, is restored to a condition where it is in strict conformity with the original last, considerable discomfort is experienced by the wearer, and this due to the worn or roughened and cracked condition of said insole. Furthermore, as will be obvious, the results of wear produced by one person are never the same as those produced by another, and unless these individual results of wear are removed in repairing, the shoes thus repaired cannot possibly be worn with any degree of comfort by anyone other than the original wearer, and even the original wearer experiences discomfort in this regard for the reasons just stated.

In the present embodiment of the invention, a shoe is provided which is of improved construction in so far as durability, comfort and waterproofing qualities are concerned, and one in which the secondary insole or layer is effectively held in a normal fixed relation within the shoe for the ordinary and usual uses, and yet at the same time the structure is such as to render the art of shoe repair a comparatively easy and practical operation, in so far as the restoring of the inner face of the insole structure is concerned. As for instance, the secondary insole or layer, when the same has become worn, may be removed from the shoe, and replaced by a new layer, body or filler, according to the method disclosed in my said co-pending application, or in fact in any other preferred manner, thus restoring the shoe to a condition where it is in strict conformity with the original last, and where the size of the repaired shoe can be easily made the same as that originally. To facilitate the removal of the worn secondary insole or layer a line of perforations may be formed in the flexible strip 7, such perforations being shown in Fig. 4, in which event the layer may be easily ripped out along said line of perforations. This line of perforations is located at such a point in the strip that when the strip is in its proper position within the finished shoe, said perforations lie about opposite the extreme edge of the usual insole, and, therefore, do not in any way hinder the waterproofing function of said strip.

In Fig. 5 of the drawing I have illustrated an embodiment of my invention, but in this instance the usual insole 2 is not dished, and there is no cushion or plastic material incorporated between the two insoles, the inner faces of said insoles lying in close contact with each other, as clearly shown in the drawing. When the secondary insole or layer shown in this figure becomes worn or otherwise unfit for use as described in connection with the other figures of the drawing, said layer may be removed and replaced by a new layer, body or filler, thus restoring the insole structure to a condition where it is in strict conformity with the original last.

It is to be noted that the secondary insole structure is stitched or sewed to the upper, usual insole, and welt, only from the toe portion of the shoe back to a point slightly beyond the instep, and that the various elements of the heel portion of the shoe are held together by means due to the usual nailing operation. In this connection, and under the conditions just stated, I am enabled to leave the heel portion of said secondary insole or layer temporarily free where it may be turned back out of the way or bent to a position where it will not be affected by the nailing or heeling operation, and do not secure the same in fixed relation within the shoe until the heeling operation has been performed; In this way a perfectly smooth layer at the heel portion of the shoe is provided, the same being free from nails or other injurious fastening de vices. To facilitate the bending back of said layer, 1 provide a score 12 or weakened portion transversely across the under side of the layer at a point as indicated in Fig. l of the drawing. After the heeling operatlon the layer may be bent back to normal position and fixedly secured wlthin the shoe .by means of an adhesive composition or in any preferred manner.

hat I claim is:

l. A shoe having a main insole, a supplemental insole, and a waterproof strip securing the supplemental insole on top of the main sole, the said strip being readily torn but having the tear restricted to a prescribed line.

2. A supplemental insole provided with a waterproof marginal attaching strip readily torn but positively restricting the tear to a line adjacent the edge of said insole.

8. A shoe having a main insole, a supplemental insole, and a water proof strip readily severable along a prescribed line and securing the supplemental insole 011 top of the main insole.

4;. A supplemental insole provided with a waterproof marginal attaching strip readily severable along a line adjacent the edge of the said insole when the latter forms a part of a finished shoe.

5. A supplemental insole having a marginal attaching strip made of rubberized material and perforated along a line adjacent the edge of the said insole.

6. A. shoe comprising an outer sole, a main insole, a supplemental insole, the main insole being dished on its upper face, means securing the two insoles together at their -marginal edges, and a cushion carried between the two insoles and lying in the dished portion of the main insole, whereby resiliency is given to the supplemental insole without increasing the thickness of the shoe between the top face of the supplemental insole and the bottom face of the outer sole. 7

7. A shoe including an outer sole,a main insole, a supplemental insole, a waterproof strip securing the supplemental insole to the main insole at the marginal edges of the two, the main insole being dished on its upper face, and a cushion carried between the two insoles and lying in the said dished portion, whereby resiliency is given to the supplemental insole without increasing the thickness of the shoe between the top face of the supplemental insole and the bottom face of the outer sole.

8. A shoe including a main and a supplemental insole, and a strip engaging the marginal edge of the main insole and secured to the under face of the supplemental insole by a hidden seam, the strip being readily severable along a line adjacent the edges of the two said insoles.

9. A shoe including a main and a supplemental insole, and a strip engaging the edge of the main insole and the under face of the supplemental insole, the strip being secured to the said latter insole by a hidden seam and being provided with perforations formed on a line adjacent the edges of the tWo insoles, whereby the tWo insoles may be readily torn apart. a

10. A shoe including a main and a supplemental insole, the main insole being dished on its upper face,a cushion lying in the dished portion of the main insole, and a strip securing the supplemental insole on top of the main insole and the cushion at the marginal edges of the two insoles, the said strip being readily severable along a line adjacent the edges or" the two said insoles.

In testimony whereof I aflix my signature in presence of two Witnesses.
